H. hyalinatus is quite a distinctive species in the east. In the female the clypeus and paroccular areas are roughly, but distinctly pitted. Also, the interpit spaces on the pleura are shiny. This is a very distinctive characteristic. Be sure to also check for this character if you think you have a female H. hyalinatus. (DL)
